how much to repair cpl small tears in roof and below window conway folding ?

You haven't told the age or selling price of the unit.
Take digital pics show at caravan garage/service centre. Be prepared to accept sellers 'First buyer takes it as is it will be sold'. That's fair as you may not go back. I had it with two caravans now won't wait for prospective buyers saying 'I'll be back' first to come with money its theirs .
